Description

La présente invention concerne un dispositif de distribution de produit fluide, et plus particulièrement un tel dispositif comportant une pompe ou une valve actionnée manuellement.The present invention relates to a fluid dispenser device, and more particularly to such a device comprising a pump or a manually operated valve.

Il est connu d'utiliser des pompes ou des valves pour distribuer de manière dosée du produit fluide (liquide, crème ou poudre), notamment dans le domaine de la pharmacie, de la parfumerie et de la cosmétique. En particulier dans le domaine de la pharmacie, il peut être très important d'éviter tous risques de surdosage et/ou de sous-comptage. Avec une valve, fonctionnant au moyen d'un gaz propulseur, le problème concerne surtout le comptage des doses émises, et il est souvent nécessaire d'éviter tout risque de sous-comptage pour éviter que l'utilisateur ne se retrouve avec un dispositif vide alors qu'il pense qu'il reste quelques doses à distribuer. En effet, des systèmes de comptage sont généralement associés à ces valves pour compter les doses émises, ces systèmes étant généralement actionnés par le déplacement relatif entre le réservoir et la soupape de la valve. Des problèmes peuvent se poser en cas d'actionnement partiel ou interrompu, qui peut provoquer une expulsion de dose, partielle ou non. Des compteurs compliqués ont été proposés pour prendre en compte ce problème, mais leur fiabilité impose une complexité et donc un coût élevé. Lorsque l'on utilise une pompe, et notamment les pompes de nouvelle génération, il peut se poser un autre problème en plus du risque de sous-comptage. En effet, la pulvérisation peut être tellement fine que la distribution de la dose n'est pas toujours ressentie par l'utilisateur. Ceci est notamment vrai avec certaines pompes de distribution nasales. Dans ce cas, si il n'y a aucune indication donnée à l'utilisateur pour lui indiquer que la dose à bien été distribuée, il y'a un risque que l'utilisateur actionne à nouveau le dispositif en pensant que son premier actionnement a été inefficace. Ceci entraîne un risque de surdosage, qui peut être néfaste pour sa santé.It is known to use pumps or valves to dispense metered fluid (liquid, cream or powder), especially in the field of pharmacy, perfumery and cosmetics. Especially in the field of pharmacy, it can be very important to avoid any risk of overdose and / or under-counting. With a valve, operating by means of a propellant gas, the problem concerns especially the counting of the doses emitted, and it is often necessary to avoid any risk of under-counting to avoid that the user is left with an empty device while he thinks that there are some doses left to distribute. Indeed, counting systems are generally associated with these valves for counting the doses issued, these systems being generally actuated by the relative displacement between the reservoir and the valve of the valve. Problems may arise in case of partial or interrupted actuation, which can cause partial or no dose expulsion. Complicated counters have been proposed to take into account this problem, but their reliability imposes a complexity and thus a high cost. When using a pump, including new generation pumps, there may be another problem in addition to the risk of under-counting. Indeed, the spraying can be so fine that the distribution of the dose is not always felt by the user. This is especially true with some nasal delivery pumps. In this case, if there is no indication given to the user to indicate that the dose has been correctly dispensed, there is a risk that the user will operate the device again, thinking that his first actuation has was ineffective. This leads to a risk of overdose, which can be harmful for his health.

La présente invention a pour but de fournir un dispositif de pulvérisation de produit fluide qui ne reproduit pas les inconvénients susmentionnés.The present invention aims to provide a fluid spray device that does not reproduce the aforementioned drawbacks.

En particulier, la présente invention a pour but de fournir un dispositif de pulvérisation de produit fluide comportant une pompe ou une valve qui évite tout risque de surdosage et/ou de sous-comptage des doses émises.In particular, the object of the present invention is to provide a device for spraying a fluid product comprising a pump or a valve which avoids any risk of overdose and / or under-counting of the doses emitted.

La présente invention a également pour but de fournir un tel dispositif qui soit simple et peu coûteux à fabriquer et à assembler, ainsi que sûre et fiable à utiliser.The present invention also aims to provide such a device that is simple and inexpensive to manufacture and assemble, as well as safe and reliable to use.

La présente invention a donc pour objet un dispositif de distribution de produit fluide tel que décrit dans la revendication 1. Des modes de réalisation avantageux sont décrits dans les revendications dépendantes.The present invention therefore relates to a fluid dispenser device as described in claim 1. Advantageous embodiments are described in the dependent claims.

D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement au cours de la description détaillée suivante faite en référence aux dessins joints, donnés à titre d'exemples non limitatifs, et sur lesquels :

  • la figure 1 est une vue schématique en section transversale d'un dispositif de pulvérisation selon un mode de réalisation,

  • la figure 3 est une vue similaire à celle de la figure 1, montrant une variante de réalisation,
  • la figure 4 est une vue similaire à celle de la figure 1, montrant un mode de réalisation de l'invention, et
  • la figure 5 est une vue de détail agrandie d'une partie de la figure 4.
Other features and advantages of the present invention will appear more clearly in the following detailed description given with reference to the accompanying drawings, given by way of non-limiting examples, and in which:
  • the figure 1 is a schematic cross-sectional view of a spraying device according to an embodiment,
  • the figure 2 is an enlarged detail view of some of the figure 1 ,
  • the figure 3 is a view similar to that of the figure 1 , showing an alternative embodiment,
  • the figure 4 is a view similar to that of the figure 1 , showing an embodiment of the invention, and
  • the figure 5 is an enlarged detail view of some of the figure 4 .

En référence à la figure 1, il est représenté un organe de distribution qui est une pompe 10, sur laquelle est assemblée une tête de distribution 20 pourvue d'un orifice de distribution 25. La pompe peut être d'un type quelconque, et la structure interne de cette pompe ne sera donc pas décrite plus amplement ci-après. La présente invention s'applique notamment, mais pas exclusivement, aux pompes de distribution qui sont adaptées à distribuer de manière très finement pulvérisée une dose de produit fluide à chaque actionnement. La tête de distribution 20 représentée sur la figure 1 est une tête de distribution nasale, et elle est utilisée pour actionner manuellement la pompe 10. Bien entendu, la présente invention n'est pas limitée à l'exemple représenté sur la figure, mais différentes variantes de réalisation sont envisageables. La pompe 10 est destinée à être assemblée sur un réservoir (non représenté), d'une manière quelconque connue.With reference to the figure 1 , there is shown a dispenser member which is a pump 10, on which is assembled a dispensing head 20 provided with a dispensing orifice 25. The pump can be of any type, and the internal structure of this pump does not will not be described in more detail below. The present invention applies in particular, but not exclusively, to dispensing pumps which are adapted to distribute in a very finely sprayed manner a dose of fluid product with each actuation. The dispensing head 20 shown on the figure 1 is a nasal dispensing head, and it is used to manually actuate the pump 10. Of course, the present invention is not limited to the example shown in the figure, but various embodiments are conceivable. The pump 10 is intended to be assembled on a reservoir (not shown), in any known manner.

Selon l'invention, le dispositif comporte des moyens de détection de distribution 30, 31 qui sont adaptés à détecter la distribution d'une dose de produit. Ces moyens de détection 30, 31 sont de préférence adaptés à délivrer un signal utilisé pour informer l'utilisateur qu'une dose de produit a été effectivement distribuée par ladite pompe. L'information de l'utilisateur peut être réalisée de diverses manières, par exemple au moyen d'un dispositif d'affichage. En variante, on pourrait envisager d'utiliser des moyens d'informations sonores ou similaires pour indiquer à l'utilisateur la distribution de la dose. Avantageusement, le signal émis par les moyens de détection de distribution 30 pourrait également être utilisé pour actionner un compteur de doses. Ainsi, dans le cas d'une pompe de distribution dans laquelle la dose est si finement pulvérisée que l'utilisateur ne se rend pas compte de cette distribution, la présente invention permet d'éviter tout risque de surdosage en informant l'utilisateur que la dose a bien été distribuée.According to the invention, the device comprises distribution detection means 30, 31 which are adapted to detect the distribution of a dose of product. These detection means 30, 31 are preferably adapted to deliver a signal used to inform the user that a dose of product has actually been dispensed by said pump. The information of the user can be realized in various ways, for example by means of a display device. Alternatively, one could consider using sound information means or the like to indicate to the user the distribution of the dose. Advantageously, the signal emitted by the distribution detection means 30 could also be used to actuate a dose counter. Thus, in the case of a dispensing pump in which the dose is so finely pulverized that the user is not aware of this distribution, the present invention makes it possible to avoid any risk of overdose by informing the user that the dose was well distributed.

Selon un premier mode de réalisation, ces moyens de détection comportent un détecteur de pression dynamique 30 pour détecter le passage de produit entre la pompe 10 et l'orifice de distribution 25.According to a first embodiment, these detection means comprise a dynamic pressure detector 30 for detecting the passage of product between the pump 10 and the dispensing orifice 25.

Le détecteur 30 comporte de préférence un matériau piézoélectrique, avantageusement du PVDF (PolyVynil DiFluoré), qui est un matériau plastique possédant des propriétés piézoélectriques, Avantageusement, comme visible sur la figure 2, le détecteur 30 comporte un tube de PVDF fonctionnant en mode respiration.The detector 30 preferably comprises a piezoelectric material, advantageously PVDF (PolyVynil DiFluoride), which is a plastic material having piezoelectric properties, Advantageously, as visible on FIG. figure 2 the detector 30 comprises a PVDF tube operating in breathing mode.

Cette mise en oeuvre garantit une détection parfaitement fiable, même en cas de très faibles quantités expulsées.This implementation guarantees a perfectly reliable detection, even in the case of very small quantities expelled.

Comme représenté sur la figure 1, le détecteur 30 peut être disposé dans le canal d'expulsion 50 qui relie la pompe de distribution 10 à l'orifice de pulvérisation 25 du dispositif. Avantageusement, il est disposé dans un manchon 40 relié d'une part à la tige d'actionnement de la pompe 10 et d'autre part à la tête de distribution 20. Ce manchon 40 peut être emmanché autour de cette tige d'actionnement, et il peut être formé en deux parties 41, 42 emboîtées l'une sur ou autour de l'autre, le détecteur 30 étant disposé entre ces deux parties. Ceci simplifie et facilite l'assemblage du dispositif, et permet de garantir l'étanchéité.As shown on the figure 1 the detector 30 may be disposed in the expulsion channel 50 which connects the dispensing pump 10 to the spray orifice 25 of the device. Advantageously, it is arranged in a sleeve 40 connected on the one hand to the actuating rod of the pump 10 and on the other hand to the dispensing head 20. This sleeve 40 can be fitted around this actuating rod, and it can be formed in two parts 41, 42 nested one on or around the other, the detector 30 being disposed between these two parts. This simplifies and facilitates the assembly of the device, and ensures sealing.

La figure 3 montre une variante de réalisation, dans lequel l'organe de distribution est une valve 10, par exemple une valve doseuse fonctionnant en position inversée. Le détecteur 30 est mis en oeuvre de manière similaire à l'exemple précédent, à savoir sous la forme d'un tube PVDF placé dans un manchon 40 réalisé en deux parties 41, 42, et assemblé autour du puit de soupape de la valve. Dans cette application, le produit fluide est généralement une solution aqueuse, la pression maximale en sortie de la valve pouvant aller jusqu'à 1000 kPa (10 bars). Ceci implique des contraintes élevées sur le détecteur ainsi que pour l'étanchéité, et la structure décrite ci-dessus permet de s'adapter sans problème à ces contraintes pour assurer un fonctionnement fiable du dispositif de distribution, évitant tout sous-comptage et tout surdosage, même en cas d'actionnement partiel du dispositif.The figure 3 shows an alternative embodiment, wherein the dispensing member is a valve 10, for example a metering valve operating in the inverted position. The detector 30 is implemented in a manner similar to the previous example, namely in the form of a PVDF tube placed in a sleeve 40 made in two parts 41, 42, and assembled around the valve well of the valve. In this application, the fluid product is generally an aqueous solution, the maximum pressure at the outlet of the valve being up to 1000 kPa (10 bar). This implies high stresses on the detector as well as the tightness, and the structure described above makes it possible to adapt without any problem to these constraints to ensure reliable operation of the dispensing device, avoiding any under-counting and overdosing. , even in case of partial actuation of the device.

La figure 4 montre un mode de réalisation de l'invention, dans lequel les moyens de détection comportent un détecteur formé par une fibre optique 30. Cette fibre optique est de préférence associée à une membrane déformable 31, avantageusement disposée autour d'une partie du canal d'expulsion 50. Lors de l'expulsion de produit fluide, la membrane 31 se déforme, notamment sous l'effet de la pression, ce qui génère des contraintes dans la fibre optique 30, créant ainsi un signal exploitable par des moyens électroniques 60 appropriés. La mesure optique est avantageuse en terme de miniaturisation dans la mesure ou l'on utilise une fibre optique compatible avec les techniques de moulage et/ou surmoulage plastique. Avantageusement, la fibre optique 30 coopère avec la membrane 31 dans un carter 45 qui peut être solidaire de la tête de distribution 20, et dans lequel la fibre optique 30 est retenue fixement de manière à détecter tout déformation de la membrane 31. Dans cet exemple de réalisation, les moyens électriques 60 peuvent comporter un émetteur et un détecteur sensible à la variation de flux lumineux transmis pas la fibre optique 30, variation due à la contrainte générée dans la fibre. La fibre optique peut être un plastique ou en verre.The figure 4 shows an embodiment of the invention, in which the detection means comprise a detector formed by an optical fiber 30. This optical fiber is preferably associated with a deformable membrane 31, advantageously arranged around a portion of the channel of expulsion 50. During the expulsion of fluid product, the membrane 31 is deformed, in particular under the effect of pressure, which generates stresses in the optical fiber 30, thus creating a signal exploitable by appropriate electronic means 60. Optical measurement is advantageous in terms of miniaturization insofar as an optical fiber compatible with molding techniques and / or plastic overmoulding is used. Advantageously, the optical fiber 30 cooperates with the membrane 31 in a housing 45 which can be secured to the dispensing head 20, and in which the optical fiber 30 is fixedly retained so as to detect any deformation of the membrane 31. In this example embodiment, the electrical means 60 may comprise a transmitter and a detector sensitive to the variation of light flux transmitted not the optical fiber 30, variation due to the stress generated in the fiber. The optical fiber can be a plastic or glass.

De manière générale, les moyens de détection 30, 31 peuvent être connectés, via des moyens de connexion adaptés 35, à des moyens électroniques (60) qui sont adaptés à traiter le ou les signaux délivrés par ledit détecteur 30, pour informer l'utilisateur de la distribution de la dose, et/ou actionner un compteur ou indicateur de doses.In general, the detection means 30, 31 can be connected, via suitable connection means 35, to electronic means (60) which are adapted to process the signal or signals delivered by said detector 30, to inform the user. the dose distribution, and / or operate a counter or dose indicator.

Bien que la présente invention ait été décrite en référence à des modes de réalisation particuliers de celle-ci, il est entendu qu'elle n'est pas limitée par les exemples représentés sur les figures. Au contraire, un homme du métier peut y apporter toutes modifications utiles sans sortir du cadre de la présente invention tel que défini par les revendications annexées.Although the present invention has been described with reference to particular embodiments thereof, it is understood that it is not limited by the examples shown in the figures. On the contrary, a person skilled in the art can make any useful modifications without departing from the scope of the present invention as defined by the appended claims.
